Bret Victor's talk from Dropbox's DBX conference about living by a guiding principle, in his case that creators need an immediate connection to what they are making. He shows live-coding and time-manipulation demos that let ideas take form at the speed of thought.

Bret Victor's talk at CUSEC 2012 in which he argues that creators need immediate feedback and should organize their work around a guiding principle. He demonstrates live-coding and animation tools that show results as you type, and describes his own principle that creators must see what they are making.

Velcro's follow-up to its "Don't Say Velcro" ad responds to viewer feedback, with a humorous take on trademark usage and alternative names for hook and loop fasteners.

Bret Victor's talk "Inventing on Principle" argues that creators should find a guiding principle to fight for. He shows demos of immediate-feedback tools, such as live-updating code and animation editors.

UC Berkeley EECS colloquium by OpenAI's John Schulman on reinforcement learning from human feedback. He covers why RL helps with truthfulness, hallucination, and the limits of behavior cloning.

A TU Wien control-systems demo in which a triple pendulum on a cart is swung up and stabilized using constrained feedforward plus optimal feedback control. It accompanies a 2013 Automatica paper.

The opening lecture of Steve Brunton's Control Bootcamp, covering the kinds of control and why closed-loop feedback matters. It starts a series that follows the control chapter of the Brunton and Kutz data-driven science book.

A short Veritasium video explaining regression to the mean and how ignoring it leads to wrong conclusions about punishment versus reward, medical treatments and sports streaks. It uses the example of flight instructors who believed criticism works better than praise.

Paul Buchheit, creator of Gmail and founder of FriendFeed, speaks at Startup School 08 about listening to users. He covers feedback, features, aiming for 100 happy users, and treating "that's impossible" as a statement of limited experience.

A 1970 demonstration of W. Timothy Gallwey, author of The Inner Game of Tennis, teaching a complete beginner to play tennis in about ten minutes. He chats with her, feeds balls and gives positive feedback instead of instruction.

A short WIRED demo from CES 2013 of Tactus Technology's haptic touchscreen, whose panel raises physical bumps to form a keyboard.

Adam Savage answers viewer questions on dealing with condescending colleagues, focusing on dismissive phrases such as 'why don't you just' and 'I would have'. He explains why such language undermines the person receiving it.

Computerphile interviews AI safety researcher Rob Miles about ChatGPT: how it was trained with human feedback, why it tends to produce confident nonsense, and where it may or may not be dangerous.

Sabine Hossenfelder explains climate sensitivity and why recent observations suggest climate models may have underestimated warming. She says this changed her view on how worried to be.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.

Martin Jonasson and Petri Purho take a bland Breakout clone and add layer after layer of 'juice' such as easing, particles, screen shake and sound until it feels alive. A live demo makes the effect of small feedback details obvious.

Veritasium examines which experts have real expertise, drawing on chess research and work by Klein and Kahneman. It explains that expertise comes from pattern recognition built through deliberate practice in valid, feedback-rich environments.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

MIT 22.01 lecture by Michael Short explaining the Chernobyl accident technically, including RBMK reactor positive feedback, xenon poisoning and the cascade of human errors during the test.

A MIX08 session from Microsoft's Office team on how the Office 2007 ribbon was designed. It explains the user-feedback and telemetry behind it and the alternatives that were rejected.

A Startup School 2013 session where Paul Graham and Sam Altman hold live office hours with startups including CodeCombat, Flexport and others. The founders pitch and get on-the-spot feedback.

A four-minute minutephysics video arguing that causal models and causal networks let statistics infer causation from correlation. It touches on Reichenbach's principle, common causes, feedback and quantum causal discovery.

A roughly 14-minute interview with OpenBSD founder Theo de Raadt at ruBSD 2013. He talks about making painful changes, getting real feedback, mitigation techniques compared to other OSs, and virtualization.

Chamath Palihapitiya's Stanford GSB View From The Top talk on money as an instrument of change. HN mostly knows it for his remarks on social media's dopamine-driven feedback loops and regrets about Facebook.

Rick Falkvinge responds to viewer feedback on his earlier Lightning Network video and raises a flaw he says was not previously discussed. The main thread is the network's unsolved routing problem.

A TU Vienna demo of a double inverted pendulum on a cart, using constrained feedforward and optimal feedback control for swing-up and point-to-point motion.

CityNerd explains why traffic congestion grows nonlinearly as more cars use a road network, and why adding road capacity tends not to fix it. It covers the consequences for drivers, bus riders, cyclists and pedestrians, and discusses alternatives such as true bus rapid transit.
